To all whom it may concern:

Be it known that l, WILLIAM H. decrees, a citizen of the United States, and a resident of Lockport, in the county of Niagara and State of NewYork, have inve ted a new and linproved Water-Box for Ca endering-Machines, of which the following is a full,

clear, and exact description.

The invention relates to the manufacture of paper and its object is to provide a new and improved .water box more especially designed for giving a water finish to the paper while the latter passes throughthe calendering machine, and arranged to prevent leakage of the water es ecially in case the calender roll should pick up foreign matter liable to lodge between the surface of the calender roll and the water supplying strip of felt. Another object is to keep the water in the supply chamber practically at a constant level with a view to insure the application of a uniform amountof water to the paper. Another object is to'provide means for quickly attaching the water box to the bearings of the calender roll or removing it-therefrom.

With these and other objects in view, the invention consists of certain novel features of construction, as hereinafter shown and? described, "and then specifically pointed out in the claims.' i

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification; in which similar characters of reference'iudicate corresponding parts inall the views.

- Figure} is a plan view of the water box as applied to apape rcalendering machine, the standards of which are shown in section;

Fig. 2 is a sectional side elevation ofthe same on the line 22 of Fi 1;

.lFig. 3 is a similar view 0 the same on the line 3-3 of Fig. 1, and showing more particularly the fastening means for fastening the water box to the bearings of the calender roll Fig. 4 is a plan view of the bottom of the water box; and v Fig. 5 is an inverted plan view of the felt car ing top of the water box.

e peripheral face of the calender roll 10 .of a calendering machine of usual construction is engaged'by the upper end of a strip 11 of felt or other suitable fabric material disposed tan entially at one side of the roll, as plainly indicated in Fig. 2. The

strip 11 is secured to the front of the top 12 of the water box13, and which top is provided with a. water-receiving. trough or chamber 14,-the front end of which is formed by the upper portion of the strip 11. A'

Water supply pipe 15 discharges ,into the I water'chanlber l4 andis connected with a suitable source of water supply to keep the chamber 14 filled with water thus maintaining the water at 'a'constant level in the chamber 14. Suflicient water is supplied by the pipe 15 to'provide an overflow which flows down an inclined channel 16 formed in the top 12 of the water box.

the bottom 21' and provided with an outlet pipe 23 for carrying the-water ed to a suitable v, The lower end of the strip'll extends onto 'the 'upper'surface 20 of the bottom 21 of the place of discharge. In order to facilitate the I down flow of the water on the surface 20 the .under side of the top 12 is provided with spaced channels 24 leading to the gathering c 24 to connect with the receiving chamber 17 thus allowing the water to flow fromthis chamber 17 into the gathering channel 22, from whichthe water can pass to a suitable place of discharge by the outlet 'pipe 23. The top '12. is fastened in position on the bottom 21 by screws '30 and 31 orother suitable fastening devices. I

In order to support the 'water' box 13 from the journal bearings 40 of the calender roll 10 the following arrangement is made: To the bearings 40 are secured brackets 41 each rovided with an inclined guideway 42 wh1ch is narrower at the upper end than the lower end, as plainly indicated in Fig. 3.

Into the guideways 42 project extensions 43 lllll Mill lllll can be .readily adjusted relative to the calv ender roll and leakage isprevented especially in case the calender roll picks up foreign matter liable to lodge between the surface of the roll and the strip 11 of felt.

It will also be noticed thatthe water is I practically kept at a constant level in the water receiving chamber 14 to insure a uniform application of water to the paper passing over the calender roll. It will also be noticed thatthe Water box can be readily detached from the calendering machine, but when in position it moves up and down with a possible up and down movement of the calender roll.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent:

1. In a water box for a calender roll, an inclined strip of fabric material in tangential position relative to the peripheral face of the calender roll and in contact at its upper end with the peripheral face of the calender roll, and an inclined surface abutting the lower end of the said strip for carrying ofi water passing down the said strip.

2. In a water box for a calender roll an inclined strip of fabric material in tangential position relative to the peripheral face of the calender roll and having the under side of its u per end in contact with the said calender r0 1, a Water supply chamber having its forward end formed by the said strip,

and a water carrying ofi surface onto which projects the lower end of the said strip for carrying ofl the water passing down the stri I 3j ln a .Water box for a calender roll, an inclined strip of fabric material in tangential position relative to the peripheral face of the calender roll and having the under side of its upper end in contact with the said calender roll, a Water supply chamber having its forward end formed by the said strip, a water carrying ofl' surface onto which projects the lower end of the said strip for carrying ofl the water passing down the strip, an overflow chamber receiving the overflow water from the said supply chamber, and a draining chamber receiving the water from the said surface and the said overflow. v

4:. In combination, a calender roll, bearings in which the said roll is journaled, brackets attached to the bearings, and a water box adjustably secured to the said brackets.

5. In combination, a calender roll, bearings in which the said roll is journaled, brackets attached to the bearings and provided with tapering guideways, a water box having members extending into the said guideways, the water box-having a stri of felt in contact with the said roll, and we ges driven in the guideways against the said box members to adjustably and detachably fasten the water box in place.
